(tilepro_plt_entry_build): Account for new header size. (tilepro_elf_finish_dynamic_sections): Ditto. (tilepro_elf_plt_sym_val): Ditto. * elfxx-tilegx.c (allocate_dynrelocs): Use PLT_ENTRY_SIZE as size of header + tail. (tilegx_elf_finish_dynamic_sections): Account for new padding. --- bfd/elfxx-tilegx.c | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) (limited to 'bfd/elfxx-tilegx.c') diff --git a/bfd/elfxx-tilegx.c b/bfd/elfxx-tilegx.c index 1f5c4587da..c0daf18bd4 100644 --- a/bfd/elfxx-tilegx.c +++ b/bfd/elfxx-tilegx.c @@ -2470,10 +2470,10 @@ allocate_dynrelocs (struct elf_link_hash_entry *h, void *inf) /* Allocate room for the header and tail. */ if (s->size == 0) { - s->size = PLT_HEADER_SIZE + PLT_TAIL_SIZE; + s->size = PLT_ENTRY_SIZE; } - h->plt.offset = s->size - PLT_TAIL_SIZE; + h->plt.offset = s->size - PLT_ENTRY_SIZE + PLT_HEADER_SIZE; /* If this symbol is not defined in a regular file, and we are not generating a shared library, then set the symbol to this @@ -4247,6 +4247,7 @@ tilegx_elf_finish_dynamic_sections (bfd *output_bfd, bfd *dynobj; asection *sdyn; struct tilegx_elf_link_hash_table *htab; + size_t pad_size; htab = tilegx_elf_hash_table (info); BFD_ASSERT (htab != NULL); @@ -4275,10 +4276,15 @@ tilegx_elf_finish_dynamic_sections (bfd *output_bfd, tilegx64_plt0_entry : tilegx32_plt0_entry, PLT_HEADER_SIZE); - memcpy (splt->contents + splt->size - PLT_TAIL_SIZE, + memcpy (splt->contents + splt->size + - PLT_ENTRY_SIZE + PLT_HEADER_SIZE, ABI_64_P (output_bfd) ? tilegx64_plt_tail_entry : tilegx32_plt_tail_entry, PLT_TAIL_SIZE); + /* Add padding so that the plt section is a multiple of its + entry size. */ + pad_size = PLT_ENTRY_SIZE - PLT_HEADER_SIZE - PLT_TAIL_SIZE; + memset (splt->contents + splt->size - pad_size, 0, pad_size); } elf_section_data (splt->output_section)->this_hdr.sh_entsize -- cgit v1.2.1
